50 Kroner · Jotunheimen Nasjonalpark

Norway's polymer transition, which began with this 50 kroner in 2017–2018, was managed by the Norges Bank under a deliberate phased rollout — each denomination introduced separately over several years rather than all at once. The substrate is produced by CCL Secure (formerly Innovia), and the note was printed by Oberthur Fiduciaire. De La Rue had held the Norwegian contract previously, making the switch notable within the industry.

The polymer series marked Norway's first use of plastic substrate for general circulation, relatively late among Scandinavian neighbors. Finland had long since moved to euro-area notes, but Sweden's Riksbank had already completed its own polymer-adjacent redesign in cotton — making Norway's full polymer commitment the more decisive break.
